--- Overheating of Components: When exposed to high temperatures, the internal components of a switch, such as processors, memory, and power supplies, can overheat. Temperature plays a critical role in the performance and longevity of industrial grade switches, which are used in environments where extreme temperatures are common. Environmental Factors: Industrial PoE switches risk overheating from inadequate ventilation, particularly in tight spaces with poor airflow, which hampers heat dissipation and can cause components to overheat and malfunction. In the driverless mining truck dispatch system at an open-pit coal mine in Ordos, Inner Mongolia, during summer when surface temperatures reached 65°C, ordinary switches frequently crashed due to overheating, causing five mining trucks to lose navigation control. Thermochromic overtemperature indicators can be employed in several critical areas, such as the insulation of electrical cables and connectors. The switch is often located near the heat-generating part and wired to the main control circuit, making it a first-responder in thermal protection.
